Can't change Jack to 24-bits (grayed out)

[jsedwards]

I bought a ESI-Juli@ card ( http://www.esi-audio.com/products/julia/ ) specifically to record 24bits/192Khz and it was Linux compatible. It records at 192KHz just fine, but only 16-bits. When I get in the Jack Setup the "Word length" is set to 16 and is grayed out and cannot be changed.

I also booted it with AV Linux and does the same thing. The 16 word length is grayed out in the Jack setup.

Is there something somewhere I need to configure or is it because ALSA cannot use the 24-bit capability of the ESI-Julia card?

I've determined the problem is not with ALSA, I can record 24-bits with arecord with no problem.

So I don't really need to get Jack working with 24-bits, because I can record what I need with arecord.

It would be nice to know what the problem is with Jack, just in case I ever need to use it, but I can live with this for now.
